Blueberry plant named &#39;ns14-4&#39;

ABSTRACT

A new and distinct variety of blueberry plant, which is denominated varietally as ‘NS 14-4’ is described, and which produces a fruit having a very large fruit size, high fruit firmness, medium fruit acidity, and a medium to high fruit sweetness, and displaying a small dry picking scar, and a high yield, when grown under the ecological conditions prevailing near Yanchep Springs, Yanchep, Western Australia.

Latin name: ‘Ericaceae Vaccinium Hybrid’.

Varietal denomination: ‘NS 14-4’.

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new, novel, and distinct variety of blueberry plant ‘Vaccinium Hybrid’ and which has been denominated varietally ‘NS 14-4’.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The present, new variety of blueberry plant resulted from an ongoing development program of plant breeding. The purpose of this program was to improve the commercial quality of various plant varieties by creating, and releasing, promising selections of plants, including blueberries. To this end, I have made both controlled and hybrid cross-pollinations each year to produce resulting plant populations from which improved progenies are evaluated and selected.

The new blueberry plant ‘NS 14-4’ was derived from a controlled cross-pollination employing the blueberry plant ‘SC10’ [unpatented], which is the seed parent, and blueberry plant ‘NS30’, [unpatented], and which is the pollen parent, during the 2012 growing season. This first cross-pollination took place at my property, which is located at Yanchep Springs, Yanchep, Western Australia. The seed parent ‘SC10’ is characterized, at least in part, by a semi-upright growth habit, a strong vigor, an early season ripening date, and further produces large sized, firm, high sweetness, and medium acidity fruit. The pollen parent ‘NS30’, on the other hand, is characterized, at least in part, by a semi-upright growth habit, a medium vigor, a very early ripening date, and further produces medium sized, firm, high sweetness, and low acidity fruit. The seed derived as a result of the first cross-pollination from the seed parent, blueberry plant ‘SC10’, produced approximately 500 plants. These new plants were then grown at my aforementioned property, and the first fruit was evaluated during the 2014 growing season. Further, an additional assessment of these same new plants, which took place in 2014, resulted in the new variety ‘NS 14-4’ being selected for further asexual reproduction and evaluation. The present, new variety showed desirable traits suitable for a commercial blueberry variety. The present, new variety was asexually reproduced by cuttings, and the plants produced from this first asexual propagation were again evaluated during the 2014 to 2016 growing seasons. The asexually reproduced plants, which were produced from the aforementioned asexual reproduction process, were subsequently evaluated, and were found to be true to the original plant. It was my conclusion, at that time, that the variety ‘NS 14-4’ was a new, novel, and distinct variety of blueberry plant.

In relative comparison to two of the closest known varieties, that being the ‘EB 8-1’ blueberry plant (U.S. Plant Pat. No. 25,859), and ‘EB 8-46’ blueberry plant (U.S. Plant Pat. No. 26,173), the new variety of blueberry plant is clearly distinguishable. The present, new variety is distinguishable from the ‘EB 8-1’ blueberry plant (a closest known variety) in view of its bush growth habit, which expresses a semi-upright growth habit when compared to the growth habit of the ‘EB 8-1’ blueberry plant, which has a growth habit which is considered spreading. Further, the present, new variety is distinguishable from the ‘EB 8-1’ blueberry plant in view of the fruit it produces, which possesses a high fruit firmness when compared to the fruit produced by the ‘EB 8-1’ blueberry plant, which produces fruit having a medium fruit firmness. Still further, the present, new variety is distinguishable from the ‘EB 8-1’ blueberry plant (a closest known variety) in view of the fruit it produces, which possesses a very large fruit size when compared to the fruit produced by the ‘EB 8-1’ blueberry plant, which produces fruit having a large fruit size. Moreover, the present, new variety is distinguishable from the ‘EB 8-1’ blueberry plant in view of the fruit it produces, which possess a medium to high fruit sweetness when compared to the fruit produced by the ‘EB 8-1’ blueberry plant, which produces fruit having a medium fruit sweetness. Yet further, the present, new variety is distinguishable from the ‘EB 8-1’ blueberry plant (a closest known variety) in view of its bush, which does not produce flowers and fruit on the current year's shoots when compared to the bush of the ‘EB 8-1’ blueberry plant, which does produce flowers and fruit on the current year's shoots.

The present, new variety is distinguishable from the ‘EB 8-46’ blueberry plant (a closest known variety) in view of its bush, which expresses a medium vigor when compared to the bush of the ‘EB 8-46’ blueberry plant, which expresses a medium to strong vigor. Further, the present, new variety is distinguishable from the ‘EB 8-46’ blueberry plant in view of its bush growth habit, which expresses a semi-upright growth habit when compared to the bush of the ‘EB 8-46’ blueberry plant, which has a growth habit which is considered spreading. Still further, the present, new variety is distinguishable from the ‘EB 8-46’ blueberry plant (a closest known variety) in view of the fruit it produces, which possesses a medium to high fruit sweetness when compared to the fruit produced by the ‘EB 8-46’ blueberry plant, which produces fruit having a high fruit sweetness. Moreover, the present, new variety is distinguishable from the ‘EB 8-46’ blueberry plant in view of the fruit it produces, which possess a high fruit firmness when compared to the fruit produced by the ‘EB 8-46’ blueberry plant, which produces fruit having a high to very high fruit firmness. Yet further, the present, new variety is distinguishable from the ‘EB 8-46’ blueberry plant in view of its very early bloom time and pick date when compared to the ‘EB 8-46’ blueberry plant, which has an early bloom time and pick date. Even further, the present, new variety is distinguishable from the ‘EB 8-46’ blueberry plant (a closest known variety) in view of its bush, which does not produce flowers and fruit on the current year's shoots when compared to the bush of the ‘EB 8-46’ blueberry plant, which has a bush that does produce flowers and fruit on the current year's shoots.

The present, new variety is distinguishable from the ‘SC10’ blueberry plant (the seed parent), in view of its bush, which expresses a medium vigor when compared to the bush of the ‘SC10’ blueberry plant, which expresses a strong vigor. Further, the present, new variety is distinguishable from the ‘SC10’ blueberry plant in view of the fruit it produces, which possesses a medium to high fruit sweetness when compared to the fruit produced by the ‘SC10’ blueberry plant, which produces fruit having a high fruit sweetness. Still further, the present, new variety is distinguishable from the ‘SC10’ blueberry plant (the seed parent) in view of the fruit it produces, which possess a very large fruit size when compared to the fruit produced by the ‘SC10’ blueberry plant, which produces fruit having a large fruit size. Yet further, the present, new variety is distinguishable from the ‘SC10’ blueberry plant (the seed parent) in view of its very early bloom time and pick date when compared to the ‘SC10’ blueberry plant, which has an early bloom time and pick date.

The present, new variety is distinguishable from the ‘NS30’ blueberry plant (the pollen parent), in view of the fruit it produces, which possesses a medium to high fruit sweetness when compared to the fruit produced by the ‘NS30’ blueberry plant, which produces a fruit having a high fruit sweetness. Further, the present, new variety is distinguishable from the ‘NS30’ blueberry plant in view of the fruit it produces, which possesses a medium fruit acidity when compared to the fruit produced by the ‘NS30’ blueberry plant, which produces fruit having a low fruit acidity. Still further, the present, new variety is distinguishable from the ‘NS30’ blueberry plant (the pollen parent) in view of the fruit it produces, which possesses a very large fruit size when compared to the fruit produced by the ‘NS30’ blueberry plant, which produces fruit having a medium fruit size. Yet further, the present, new variety is distinguishable from the ‘NS30’ blueberry plant (the pollen parent) in view of its very early bloom time when compared to the ‘NS30’ blueberry plant, which has an early bloom time.

Having thus described and illustrated my new variety of blueberry plant, what I claim is new, and desire to secure by plant Letters Patent is:
